Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611340, here are decompositions:

19 + 8611321 = 8611340
37 + 8611303 = 8611340
43 + 8611297 = 8611340
79 + 8611261 = 8611340
139 + 8611201 = 8611340
193 + 8611147 = 8611340
223 + 8611117 = 8611340
277 + 8611063 = 8611340

Showing the first eight; more decompositions exist.
